13 year old me who anodised remote control car chassis completely agrees the process is quite simple.

In the context of a MacBook, it’s not. Removing just the aluminium components and leaving everything that doesn’t like baths undamaged is practically impossible for amateurs. I’m not sure it’s something many professionals would take on.

I think it could be possible for the bottom half. The lid would be way, way trickier (unless you have one with a broken screen already and know how to put the new one together).

I’m wondering what custom colours you could do with that process btw!

Practically anything! Vibrant colours work best, and there are techniques to do transitions, fades, and masking to get multiple colours, though I’ve never done those myself.
